Βίδα Fischer 566335 140 mm γαλβανισμένος χάλυβας 50 τεμ.

The fischer wood construction screw PowerFast II FPF II-WTP BC is a zinc-plated steel screw with a flange head, TX (star) recess drive and partial thread designed for timber constructions. With a length of 140 mm, an 8 mm thread diameter and 80 mm thread length, this screw secures wooden elements firmly together and provides increased resistance against the head pulling through the components. The design includes a patented core cutter geometry and a shank-miller for easier entry and reduced screw-in torque.

Advantages

The patented core cutter geometry enables precise milling and effective removal of wood dust, allowing small edge and center distances. The three-rib screw tip provides fast biting and pre-milling, which reduces splitting and ensures quick setting. An increased thread pitch shortens installation time, while the high-performance easy-glide coating lowers screw-in torque for smoother installation and longer battery life. The shank-miller is matched to the core-miller to further reduce driving resistance. The larger flange head yields higher pull-out resistance compared with countersunk head screws and improves the clamping of joined components.

Suitable for

• Timber framing and structural wood connections
• Attaching wooden beams, posts and plates
• Outdoor and indoor wood construction when zinc-plated steel is acceptable
• Applications requiring high head pull-through resistance and firm clamping

How to use

Place the screw so the partially threaded section spans the gap to be clamped and align the flange head with the surface of the outer component. Use a TX bit matching the star recess to drive the screw. For most timber applications the PowerFast II screw can be driven without pre-drilling; however, choose pilot holes when working near edges, with very hard wood species, or when exact positioning is required. Apply steady driving speed and monitor torque to avoid over-driving. The easy-glide coating and shank-miller reduce required force and battery consumption during installation.

Recommendations

Use zinc-plated Fischer PowerFast II screws for general timber connections where corrosion exposure is limited; for prolonged outdoor or highly corrosive environments, consider using specially coated or stainless steel fasteners compatible with structural requirements.
